| 发明名称 | Method and system for adaptively identifying signal bandwidth | ||
| 摘要 | The present invention discloses a method and system for adaptively identifying signal bandwidth. The method includes: performing digitizing intermediate frequency processing to the received signal and outputting in-phase/quadrature (I/Q) signals; identifying signal bandwidth of the I/Q signals according to at least two signal identification templates and outputting the synchronized signal flows after a successful identification. A system for adaptively identifying signal bandwidth is also disclosed. The present invention can be compatible with at least two bandwidth modes, and the software can automatically perform identification and switch of the modulation bandwidth, when manual invention is not necessary and the operation is simple. | ||
